ROMULUS P. LUDVIG, OF SAUMSVILLE, ASSIGN OR OF ONE-HALF TO SAMUEL M. LANTZ, OF EDENBURG, VIRGINIA.

DRILL-TOOTH REGULATOR ANO COMPRESSOR FOR SEEOERS.

SPECIFICATION forming part of Letters Patent No. 312,873, dated February 24, 1885. Application iled October 4, 1854. (No model.)

To all whom, it may concern:

Beit known that I, RoMULUs P. LUDWIG, a citizen of the United States, residing at Saumsville, in the county of Shenandoah and State of Virginia, have invented certain new and useful Improvements in Drill-Tooth Regulators and Compressors for Seeders, of which the following is a description.

This invention relates to that class of dero vices used to plow shallow furrows in the ground, to drop seed, such as wheat, therein, and to cover and press the earth thereon; and its object is to raise the drill or plow point at will, and to mechanically hold it raised while traveling and not in use, and to set the drill to plow deep or shallow, as may be required.

To this end my invention consists in they construction and combination of parts forniing a drill-tooth for seeders, including the 2O supports therefor, hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure l is a sideelevation of my invention, and Fig. 2 is a plan `View thereof.

D represents the boot or drilltooth, down through the interior of which the grain is dropped, as usual. The toe N of this boot is a plow-point capable of parting the earth to receive the grain. I hang this boot on a pivot, 3o E, nearly vertically over the point N between two bars, B, which aresnpported at their rear ends upon a wheel or roller, A.

F is a brace pivoted to the drill at G,whicl1 is a point on the upward arm of the drill, and provided with a series of holes, I, along its rear end. A pin, H, is placed in one of these holes to extend its ends into slots C in the bars B.

J represents two links,by which the device is drawn. The rear ends of these links are pivoted upon the pin E, and their forward ends are loosely attached to the seed-drilling machine. y

K is a fixed portion of the tooth D,extend ing forward from the top thereof in the form of a brace, and acting as such by means of the pin M, located in any one of a series of holes, L, in the brace K and resting on the links J.

The action is as follows: The pin M is of 5o some material-such as wood-easy vto be broken, and when the plow-point meets any obstacle which it cannot pass the pin M breaks, allowing the upper end of the drill to swing forward on its pivot and the lower end consequently to swing backward and drag over the obstacle. Vhen it is desired to hold the drill out ofthe ground while the machine is traveling from place to place, the rear brace,

F, is pushed forward and its pin H is placed in the rear one ofthe holes I. The drill be- 6o ing secured in iixed relation to the links Jby means of the pin M resting thereon, theforward motion of the brace F raises the drill upward. as shown in dotted lines, and thepin H,tiXed in therearhole,l,restsin therearendof the slots, thus holding the whole central portion of the device raised. Tere it not for the pin M resisting forward motion of the drill by resting on the links J, the forward motion of the brace F would nierely tip the drill forward 7O without raising it; but the forward ends ot' the links J being supported,any push forward at G tends to raise the central portion of the whole device bodily. I change the pitch ot' the drill or plow-point by placing the pin M in different holes ofthe brace K.

I am aware that a seed-drill tooth has before been hung to a horizontal bar by apivot, the said bar being supported at its rear end on a roller, and provided with a horizontal 8O slot and a brace pivoted to the drill at one end,the other end having a pin to slide in said slot; but I ain not aware that there has been used with that device a fulcrum like my forward links and pin, whereby the pushing forward ot' the said brace pivoted to the drill will raise the drill bodily.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with an earth-roller,a 9c pair of horizontal slotted bars supported at their rear ends upon the journal thereof, and a seed-drill tooth hung vertically between the forward ends of the said bars on a horizontal pivot, of a brace pivoted at its forward end to an upward arm ofthe drill-tooth,and provided with a series of pin-holes at its rear end, a pin to be placed in any one of the said holes and through the slotin the said bars, apair of connecting-links pivoted at their rear ends on the IOO same pivot on which the drill-tooth is hung and extending forward to be attached to a seeding-machine, and a brace extending forward from the upper arin of the drill-tooth, and a pin through the brace adapted to rest on the forward links, substantially as described, for 5 the purpose set forth.

2. The combination, with the roller A, the bars B, supported thereon, and provided Wit-h the slots C, of the drill-tooth D, pivoted at E between the bars B, the brace F,pivoted to the io drill-tooth at G, and provided with the holes I, and pin H, engaging the slots C and said holes I, the links J,pivoted at their rear ends at E, and the brace K, attached to the tooth D, and provided with aserics of holes,L, and the pin M, adapted to engage the said holes i 5 and to rest on the links J, as and for the purpose specicd.

ROMULUS P. LUDVIG.
